MAGDRAIN floor drains with anti-odor valve guarantee 100% protection. They use innovative technology that increases water flow capacity up to 36 L/min. The drains feature a turbine valve that rotates and creates a vortex inside the drain, resulting in a self-cleaning effect. This valve allows the turbine to rotate without any resistance. The innovative valve is not based on a spring mechanism, which over time may fail, get blocked, break, or stop working. MAGDRAIN drains use patented magnetic technology in their valves. They are supplied in a premium package and come complete with a Ø50 coupling and Q-50 valve. The magnetic valve prevents unpleasant sewer odors and also protects against cockroaches and flooding from wastewater.
